The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

JEFFREY HEMSTREET, MD appears in the CMS NPPES registry as a Emergency Medicine Physician provider holding MD credentials at 342 FAIRVIEW STREET, SILVERTON, OR, 97381, with a listed phone of (503) 873-1500. NPI 1538156179 was issued on 09/29/2005.

Medicare Part D records for calendar year 2023 show 177 prescription claims written by this provider, covering 132 Medicare beneficiaries and totaling roughly $3K in drug spend, with an opioid prescribing rate of 20.9%.

Emergency Medicine Physician is a high-volume specialty nationwide, with 64,398 enrolled providers across 56 states and an average of 352 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
